TOOL FOR REMOVING: SPRING SUPPORTS ON AXLES.

Application filed June 10, 1925.

To all whom it may concern:

Be it known that T, HERBERT A. BERKMAN, a citizen of the United States,residing in Chicago, county of Cook, State of Illinois, have invented acertain new and useful Improvement in Tools for Removing Spring Supportson Axles, and declare the following to be a full, clear, and exactdescription of the same, such as will enable others skilled in the artto which it pertains to make and use the same, reference being had tothe accompanying drawing, which forms a part of this specification.

The present invention relates particularly to tools for forcing thespring-supporting posts out of the axles of automobiles into which theyare fitted and has for its object to produce a simple and novel tool ofthis kind particularly adapted for use on Ford axles.

The various features of novelty whereby my invention is characterizedwill hereinafter be pointed out with particularity in the claims; but,for a full understanding of my invention and of its objects andadvantages, reference may be had to the following detailed descriptiontaken in connection with the accompanying drawing, wherein:

Figure 1 is a side elevation of a fragment of a Ford axle to which myimproved tool has been applied, preparatory to removing thespring-supporting post; Fig. 2 is a View looking toward the part shownin Fig. 1, from the right hand side of Fig. 1, the axle being insection; and Fig. 3 is a section taken approximately on line 3-3 of Fig.1.

Referring to the drawing, 1 represents a heavy U-shaped yoke. On thefree end of each of the arms of the yoke is pivoted a dog. Each dogconsists of a U-shaped member 2 embracing the arm on three sides, namelythe front and rear and the outer side. The two side members and thecross piece of each dog preferably lie in contact with the adjacentfaces of the yoke member on which the dog is mounted, and each dog ispivoted to its supporting arm, as indicated at 4-, to ward the upperinner corner. The extreme upper outer corner of each arm of the yoke isrounded, as indicated at 5, to permit each dog to swing from a positionin which it lies at right angles to its supporting arm, with its closedend engaged with the outer side of said arm, to a position, such asindi- Serial No. 36,212.

cated in dotted lines on the left hand side of Fig. 2. The dogs are madesufficiently long so that the inner ends or noses thereof project intothe space between the arms of the yoke when the dogs lie at right anglesto the arms as shown in full lines in Fig. 2 of the drawings. On thefront or rear, or on both sides of the yoke are lugs 6 that limit thedownward swinging movements of the inner ends of the dogs. The parts areso proportioned that when the dogs are swung untn they engage with thestops or lugs, their inner edges 7 lie approximately in the planes ofthe inner faces or sides of the arms of the yoke; thus permitting thetool to be applied laterally to an axle having an extreme width orthickness slightly less than the width 01 the opening in the yoke.

A comparatively heavy screw 8 extends upwardly through the closedportion of the yoke, midway between and parallel with the arms.

In using the tool on a Ford axle, such as shown at A in the drawings,such axle being I-shaped and having its web thickened, as indicated ata, at the point where the spring supporting post B passes through thesame; the inner ends of the two dogs are swung down so as to leave theopening in the yoke unobstructed, and the yoke is then moved upwardlyfrom underneath the axle, with the two noses of each dog lying onopposite sides of the enlargement or boss at on the axle. The dogs arethen swung into their horizontal positions so as to overlie the lowerchord of the axle. Then, upon turning the screw 8, the upper end of thelatter engages with the bottom of the post B, forcing the postupwardlyout of the axle. After the post has been removed, the yoke is liftedslightly, so as to permit the dogs to be swung into their releasepositions, where upon the yoke may be withdrawn from the axle.

It will thus be seen that I have produced a simple and rugged tool thatmay conveniently be applied to and removed from a Ford axle, for easilyforcing a spring-supporting post out of its socket.

While I have illustrated and described with particularity only a singlepreferred form of my invention, I do not desire to be limited to theexact structural details thus illustrated and described; but intend tocover all forms and arrangements which come within the definitions of myinvention constituting the appended claims.

I claim:

1. A device of the character described, comprising a U-shaped yoke, aU-shaped dog embracing the free end of each arm of the dog with its openside directed inwardly, the dogs being pivoted to swing about axes atright angles to the plane of the yoke, stops to limit the downwardmovement of the inner ends of the dogs, the closed ends of the dogscooperating with the arms on which they are mounted to limit the upwardswinging movements of the dogs to positions in which the dogs lie atright angles to said arms and project into the space between the arms,the inner ends of the dogs being shaped to lie approximately in linewith the inner faces of said arms when the dogs are engaged with saidstops, and a screw extending through the closed end of the yoke betweenand par allel with the arms thereof.

2. A device of the character described, comprising a U-shaped yoke, adog mounted on the free end of each arm of the yoke so as to be capableof swinging downwardly from a position in which it lies transversely ofthe arm and extends inwardly toward the opposite arm, a stop on each ofthe arms to prevent the dogs from swinging upwardly past the aforesaidposition, other stops on the arms for limiting the downward swingingmovement or the dogs to positions in which they lie outside of the innerfaces of the arms on which they are mounted, and a screw extendingthrough the connectin piece of the yoke between said arms and arrangedparallel to said arms.

In testimony whereof, I sign this specification.

HERBERT A. BERKMAN.
